RESILTFNT AXLE MOUNT FOB MOTOR VEHICLES.

Application filed April 12, 1928, Serial No. 101,511, and inCzechoslovakia February 1, 1925.

The invention relates to the mounting of non-driven resiliently mountedswivelling or oscillating shaft-portions or half axles for motorvehicles having a medial supporting member. The front part of thissupportin member is constituted by the motoran gear-case, which may ifdesired be combined to form a single unit.

' Accordin to the invention the oscillatin or swivellin half axles,which are jointed to the me ial supporting member of the vehicle, areconnected by means of joints and resiliently mounted strut members withthe upper part of the supporting member 1 whereby a strong, resistantand at the same time light and simple construction of good supportingpower and strong shock absorbing spring action is obtained. Accordingfurther to the invention in order that the resilient shock-absorbingsupport of the shaft portions at the upper part of the framework may notunduly and unfavourably strain the material of the latter, the point ofsupport of the spring shock-absorb- 1ng members on the framework isconnected with the lower bearing joint of the shaft portion by means ofa tie rod adapted to take up the tensional stress which arises.

One constructional form according to the invention is illustrateddiagrammatically by way of example in the accompanying, drawings, inwhich:

Fig. 1 is a front view of the arrangement of the front wheels of anautomobile, and

Fig. 2 is a plan corresponding to Fig. 1 with the spring members omitteIn the example illustrated a gear case 2 is directly attached to a motorcase 1 both cases 1 and ,2 forming at the same time the front part of amedial supporting member of the vehicle. On the lower part of the motorcase 1 joints 3, 4 are arranged close beside one another and serve forthe reception of non-driven shaft portions or halfaxles 5, 6, whichlatter are forked (Fig. 2) and carry at their free ends bearings 7 forthe front wheels 8, 9 of the vehicle. End lugs 11, 12 are jointed ineyelets 10 near the free ends of the half-axles 5 and 6 and similar endlugs 13, 14 are jointed to the two sides of the upper part 1 of theframework. Pressure springs 15 are arranged between the lugs 11 and 13and between the In 12 and 14 respectively, said s rings eing carried onguides 16 each consisting of two parts telescopically connected with oneanother. One of these guides 16 has its one '-part connected to the lug11 and its other part to the lug 13, whilst the other guide 16 as itsone part connected to the in 12 and its other part to the lug 14. Thepints of the tugs 13, and 14 are connected with the Joints 3 and 4 ofthe half-axles b means of tension rods 17 and 18.- Besides t is the pinsof the lugs 13 and 14 are connected b means of a common rod member ormom rs 19. The arrangement of the parts is made in such a way thatneither the tension rods 17 and 18 nor the rod member or members 19 comein the way of'the motor in the case. For this purpose the guides 16 mayfor example be forked in similar manner to the shaft portions from thelugs 11 and 12 respectively and provided with two springs for eachhalf-axle.

The mounting and spring suspension of the half-axles may be effected onthe gear case 2 or on the common motor and gear case;

I claim: a

1. In a motor vehicle, a medial sup rting frame, .a air of independentlyswivelling half-axles avin their inner ends pivotally connected to saiframe and an extensible strut pivotally connected between the outerportion of each half-axle and said frame for yieldingly .maintainingsaid half-axles in normal position, the said strut for each halfaxlebeing connected to said frame at a point vertically spaced from thepivoted inner end of the respective half-axle.

2. The structure as in claim 3 wherein each of said axles is pivoted tothe said frame below the corresponding point of connection of therespective strut members.

3. The structure as in claim 3 in combination with tension membersconnecting the pivot of each halfaxle to the inner pivot of thecorresponding strut member.

4. In a motor vehicle a longitudinal medial supportin mem a pair ofswivelling half-a es, each half-axle comprising a rigid V fork, abearing at the vertex of each fork for a vehicle wheel, and pivotalconnections between the ends of each fork and the medial supportingmember.

5. The structure as in claim 7 wherein extensible strut members connectthe outer portion of each fork with the medial supportin member at tsvertioall spaced from he pivotal connections-of t e forks therewith. v Ip g 6. Mounting -for non-driven, resiliently mounted pivoted half-axlesfor motor vehicles having a longitudinal medial supportm member, a motorcase and-a gear case, bot cases forming the front part of said medialsupporting member, oscillating half-axles pivoted to one of said cases,and extensible strut members act upon by compression springs connectingthe outer end of each half axle with an upper part of the case.

7. Mounting for non-driven, resiliently mounted pivoted half-(Ides formotor vehicles having a longitudinal medial support' member, a motorcase and a gear case, bot cases forming the front part of said medialsupporting member, the oscillating half-axles pivoted to one of saidcases, extensible strut members acted u on by compression springs forconnecting the outer end of each halfaxle with an upper part of thecase, and tension rods, connecting the supporting point of the resilientstrut member on the case with $5 the pivot of the half-axle on saidcase.
